Parallel Connector

Use the 25-hole parallel connector to attach a parallel device to the computer. The parallel connector is

used primarily for printers. The parallel connector transmits data in parallel format, where 8 data bits

(one byte) are sent simultaneously over eight separate lines.

The parallel connector can also be configured for compatibility with the PS/2 standard. Support for the

EPP feature improves network adapter performance (adapters connect to the computer's parallel

connector and require the appropriate software drivers from the adapter's manufacturer).

If you reconfigure your hardware, you may need pin number and signal information for the parallel

connector.
